HTTP Respond and Redirect Together

Hi -

I need to be able to send an HTTP 404 along with a redirect. Can this be done? Why I want to do this… My OOS page is hosted externally. Currently I have an iRule that will send a 404 with content that is src=“http://myoospage.othersite.com” This doesn’t work for ssl connections, though, because it’s attempting to use insecure content.

Any suggestions? I’m thinking if I can respond with a 404 and redirect that would work. The 404 response is a requirement.

Thanks!

Maybe something like this…

when HTTP_RESPONSE {
if { ([HTTP::status] equals "404") } {
    HTTP::respond 404 content " "
    }
}

Sorry, it didn’t like the html tags. Anyway, you could send the 404 back to the client that includes an html redirect such as meta http-equiv=refresh content=0;url=[destination_url]

Hey Tim, So this worked…kind-of :slight_smile: It only works when hitting the site using Firefox. Chrome just spits out what I have in quotes IE loads the page partially. I’m a bit of a novice here… any ideas on what else I may need? Here’s my iRule as it looks now: when HTTP_REQUEST { if { ([active_members [LB::server pool]] < 1 ) } { HTTP::header insert Edge-Control bypass-cache HTTP::respond 404 content " " } }

oops, tags got me too… In quotes I have the following with the brackets replaced with http://mystatus.othersite.com meta http-equiv=refresh content=0;url=[destination_url]

You’ll need to add all the opening and closing html tags, such as… html head meta http-equiv=refresh content=0;url=[destination_url] head html

Which when added together becomes;-

when HTTP_REQUEST {
        set 404_page " " 

    if {![active_members [LB::server pool]]} {
        HTTP::respond 404 content $404_page Edge-Control "bypass-cache" Cache-Control "nocache"
        return
    }
}

OR

when HTTP_RESPONSE {
        set 404_page " " 

    if { [HTTP::status] == 404} {
        HTTP::respond 404 content $404_page Edge-Control "bypass-cache" Cache-Control "nocache"
        return
    }
}

Thanks Tim K! It works.

Final iRule is like this: when HTTP_REQUEST { if { ([active_members [LB::server pool]] < 1 ) } { HTTP::header insert Edge-Control bypass-cache HTTP::respond 404 content " " } }
